The article considers the issues of using compressed natural gas as alternative vehicle fuel and reducing the toxicity of diesel engine exhaust gases. Special attention is paid to the problems of nitrogen oxides generation and decomposition in the cylinder of a diesel engine operating on natural gas, its impact on the combustion process. The article presents the results of experimental studies of the effect of compressed natural gas and recycling on the effective characteristics, the toxicity and opacity of exhaust gases. Characteristics of heat generation are studied in details and determined, the values of volume content of nitrogen oxides in the cylinder against the change of crankshaft rotation angle are obtained.
